Abstract: PCT No. PCT/GB80/00184 Sec. 371 Date Jun. 17, 1981 Sec. 102(e) Date Jun. 17, 1981 PCT Filed Oct. 28, 1980 PCT Pub. No. WO81/01259 PCT Pub. Date May 14, 1981.In manufacture of a can body by drawing a cup from a blank and subsequently redrawing the cup, one or more redrawing steps are performed by pulling the sidewall of the cup (2) by means of a punch (12) through an S-shaped path (30,24,31), whereby the wall is bent first in one direction and then in the other, to reduce its diameter, which is then reduced further in a convergent portion (20) of the die (10). The bending induces back tensions which stretch the metal and reduce its wall thickness.

Title: Production of neutral calcium hypochlorite from its dibasic salt
IPC: C01B11/06
Filed: 1982-11-03
Abstract: A process for producing neutral calcium hypochlorite comprises admixing lime, an alkali metal hypochlorite and dibasic calcium hypochlorite crystals in a mixing zone slurry. The mixing zone slurry is reacted with chlorine to form a paste of neutral calcium hypochlorite. The paste is then separated into a cake of neutral calcium hypochlorite and a paste liquor. A slurry of lime is fed to a crystallizer to react with the paste liquor to form a slurry of dibasic calcium hypochlorite crystals in a mother liquor. Crystals of dibasic calcium hypochlorite are then separated from the dibasic mother liquor and recycled to the mixing zone. The process of the present invention provides an efficient method of recovering calcium hypochlorite values from process liquors while reducing energy costs expended in the recovery. The process further provides rapid recovery of dibasic calcium hypochlorite for reuse in a neutral calcium hypochlorite process by optimizing separation rates.

Patent ES-8704019-A1 (ES)
Title: Method for detecting and obtaining information about changes in variables.
IPC: G01M3/18
Filed: 1984-06-29
Abstract: Method and apparatus for detecting and obtaining information about (particularly locating) an event (E), i.e. a change in a variable, for example a liquid leak. In a preferred embodiment, two conductors (11,12) follow an elongate path and are connected to each other through a power source, preferably a constant current source (15). In the absence of an event, the two conductors (11, 12) are electrically insulated from each other at all points along the path. When an event (E) occurs, the two conductors (11, 12) become electrically connected at a connection point at which the event occurs, thus completing a test circuit in which a current of known size then flows. When using a constant current source (15), the size of the current does not depend on the resistance of the connection. One of the conductors is a locating member having known impedance characteristics along its length, and by measuring the voltage drop between the connection point and one end of the locating member, the location of the event can be calculated. The voltage drop can conveniently be measured by means of a third conductor which connects, via a high impedance a voltmeter (14), the ends of the locating member.

Title: Process and apparatus for the electrolytical deposition of metals.
IPC: C25D5/08
Filed: 1984-11-08
Abstract: The strip enters the electrolyte (in 8) in vertically downward direction and, after passing around a roller (10), leaves the electrolyte (in 12) in vertically upward direction.

Title: Digital rod position detector system.
IPC: G01D5/20
Filed: 1985-09-30
Abstract: Coils placed at spaced locations along the path of an axially movable magnetically permeable and/or electrically conductive rod, which changes the impedance of each coil as it passes through, are connected in sets with each set comprising two series connected groups of equal numbers of parallel connected, non-adjacent coils energized by an a-c source. The voltage at the common node of each set of coils, which fluctuates as equal and unequal numbers of coils in the two groups in a given set are penetrated by the end of the rod, is compared with the voltage at the common node of a pair of series connected resistors, also energized by the a-c source, to generate one digit of an unambiguous, multi-digit, digital rod position signal. Since only one signal wire to the remote electronics is required for each set of coils, and since they only carry a voltage signal, the required wiring is minimized. Compensation is provided to maintain the location of the rod end relative to each coil at which the digital signal changes state despite variations in temperature and voltage.

Title: A method of controlling intermittant voltage supply to an electrostatic precipitator.
IPC: B03C3/68
Filed: 1985-12-11
Abstract: In the method of controlling the period length of an intermittent voltage supply to an electrostatic precipitator, a search procedure is carried out at predetermined time intervals or at time intervals determined by one or more continuously monitored/measured precipitator or operational parameters. During the search procedure either the number of system voltage half-periods during which the power supply to the precipitator is cut off (the length of the non-conduction (np) period), or the number of system voltage half-periods during which the power supply supplies current to the precipitator (the length of the conduction period), are changed according to a predetermined scale or to a scale determined by one or more precipitator or operational parameters. The charge transmitted per system half-period is current in the precipitator divided by the total number of half-periods of conduction per second. The search is stopped when the relation between the charge transmitted per system half-period and the maximum voltage at transition from one search stage to the succeeding one remains constant or increases and the number of system half-periods, of conduction or non-conduction (np) respectively, existing when the search is stopped is maintained until the next search procedure.
